Description
Technical field
The utility model belongs to PTC perforated pipe stake technical fields, and in particular to a kind of reinforced PTC perforated pipes stake.
Background technology
In early days, for China's Coastal Areas mud Unfavorable geology the characteristics of, by PC tube pile structures and manufacture craft
Transformation, have developed pretensioning prestressed concrete thin-wall pipe pile (abbreviation PTC pile tubes).PTC types pile tube is as a kind of strength of the mixing pile
High rigid pile, it is widely used by its function and advantage in pile foundation engineering.
But in work progress, static pressure pile-sinking or hammer piling mode are either taken, it can all produce more obvious
Soil compaction effect phenomenon, and crackle is easily detected on pile body.Its reason is analyzed, mainly in pile driving process, soil around pile
More pore water can not dissipate in time caused by body, form higher excess pore water pressure, to pile body and the building of surrounding
Environment generates influence.In addition, for the deep soft soil foundations such as highway, high-speed railway, road in airport, control ground sinks
Drop, it is more to control its settlement amount after construction in settlement amount after construction critical field.It is and main former caused by settlement of foundation
Because being due to the discharge of the soil body pore water under outer load action.Therefore, if needing to construct in embankment, dykes and dams, field road etc.
Phase produces more settling amounts as far as possible, should be by the discharge as much as possible of native pore water, to reduce the water content of soil, then its work
Settling amount will be reduced afterwards, so as to reach the purpose of control settlement and settlement amount after construction.
Therefore, generating PTC perforated pipe stakes in the prior art, i.e., outer water seepage hole is opened up on the pile body of PTC pile tubes, then it is native
Pore water will penetrate into pile tube inner chamber by outer water seepage hole, be minimized the water content of soil, native intensity is improved, ground
Base bearing capacity also strengthens therewith.
Show however, the outer water seepage hole set by PTC perforated pipe stakes makes pile tube bearing capacity generate reduction to a certain extent
As.Therefore, how while native pore water is discharged, reduce the influence that soil compaction effect is brought in pile driving process, ensure pile sinking
Quality, pile tube bearing capacity is improved, be the technical problem that those skilled in the art have been working hard solve.
In order to effectively reduce the influence that soil compaction effect in pile driving process is brought, accelerate the dissipation of excess pore water pressure,
Ensure pile sinking quality, this just has to take certain measure.
Utility model content
In order to overcome and avoid weak point of the prior art, the present invention proposes a kind of reinforced PTC perforated pipes stake.This
Utility model is not only able to effectively reduce the influence that soil compaction effect in pile driving process is brought, and accelerates disappearing for excess pore water pressure
Dissipate, and ensure that pile sinking quality, improve pile tube bearing capacity.
In order to realize the purpose of this utility model, the utility model employs following technical scheme：
A kind of reinforced PTC perforated pipes stake, forms and outer water seepage hole is provided with the outer tube wall of pile tube, pile tube is in the outer tube

Wall is connected and pile tube inner chamber is divided into the less adapter cavity of area and the larger main chamber of area；If inner tubal wall and outer tube wall it
Between the adapter cavity that surrounds be connected with the outer water seepage hole, then the bottom of chamber portion of this adapter cavity is arranged to closed, and surrounds this mistake
Cross on the inner tubal wall of chamber and be provided with the interior water seepage hole of connection adapter cavity and main chamber.
Preferably, said inner tube wall is arranged to the smooth arc surfaced from the lateral main chamber side protrusion of adapter cavity one.
As a kind of preferred scheme of the present utility model, the outer water seepage hole is distributed in the outer tube along pile tube axisymmetrical
The both sides of wall, the adapter cavity surrounded between said inner tube wall and outer tube wall are connected with the outer water seepage hole, and inner tubal wall edge pipe
Stake axisymmetrical is distributed in the both sides of the outer tube wall.
It is further preferred that the outer water seepage hole for being distributed in outer tube wall the same side is in from top to bottom column-shaped along pile tube axis
Arrangement, and the outer water seepage hole is arranged along the outer tube wall in even column.
As another preferred scheme of the present utility model, be distributed in the outer water seepage hole of outer tube wall the same side from upper and
It is lower to be arranged along pile tube axis in column-shaped, and the outer water seepage hole is uniformly arranged along the outer tube wall in odd column；Said inner tube
The adapter cavity surrounded between wall and outer tube wall is connected with the outer water seepage hole.
Preferably, the outer water seepage hole for being distributed in outer tube wall the same side is arranged along pile tube axis in column-shaped from top to bottom,
The interior water seepage hole of connection corresponding with outer water seepage hole is then arranged on said inner tube wall along pile tube axis in column-shaped from top to bottom.
It is further preferred that the interior water seepage hole on same inner tubal wall is arranged to two row, and seeped water in this two row
Hole is symmetrically distributed in the both sides of inner tubal wall.
Still more preferably, the single-row outer water seepage hole and the quantity phase of single-row interior water seepage hole being connected by same adapter cavity
Together, this single-row outer water seepage hole is equal with the distribution height of single-row interior water seepage hole, and the spacing of adjacent outer water seepage hole interior is oozed with adjacent
The spacing in water hole is also equal.
The beneficial effects of the utility model are：In the utility model is additionally arranged in the pile tube inner chamber of PTC perforated pipe stakes
Tube wall, and the adapter cavity for making to surround between inner tubal wall and outer tube wall is connected with the outer water seepage hole, the utility model also including
It is provided with interior water seepage hole on tube wall accordingly, while the utility model is by the bottom for the adapter cavity being connected with the outer water seepage hole
It is arranged to closed.It is the then reinforced PTC perforated pipes sunk pile construction period in the utility model, outer on pile tube outer tube wall
Water seepage hole can allow more pore waters, mud in pile peripheral earth to enter adapter cavity, then escape and enter pipe by adapter cavity
In stake main chamber, finally the water in pile tube main chamber is extracted out using micro pump.The utility model can be effectively reduced stake week
The moisture content of the soil body, the shearing strength of pile peripheral earth is improved, strengthens the bearing capacity of pile foundation, reached mitigation pile tube soil compaction effect,
Reduce the purpose that pile sinking is endangered adjacent stake and Adjacent Buildings；In addition, the utility model can also effectively improve PTC perforated pipes
The stiffness of structural member of stake, PTC pile tubes are reduced because perforate causes the degree of bearing capacity reduction, during improving PTC perforated pipe pile driving constructions
Easily there is the problem of pile body crackle, substantially increase the durability and reliability of PTC perforated pipe stakes.
